Stancor is a brand of electronic components originally established by Hamilton Standard (a division of United Technologies), later becoming part of White-Rodgers under Emerson Electric Co.

Waldom Electronics is headquartered in Rockford, Illinois, USA, and acts as a master distributor and manufacturer of electronic components. The Stancor product portfolio includes power transformers, audio transformers, isolation transformers, and chassis-mount transformers, with series such as SP (single primary) and GP (general purpose) widely used in industrial controls, HVAC systems, and consumer electronics. Relay offerings span general-purpose, power, and solid-state types for diverse switching applications. The brand also supplies solenoids, filter chokes, and custom magnetic components to OEMs. Through its GC/Waldom division, Waldom Electronics distributes Stancor products globally along with interconnect, electromechanical, and passive components. Stancor transformers are recognized for reliable, rugged design and remain a leading choice in replacement and aftermarket segments. With substantial inventory and technical support, Waldom Electronics ensures rapid availability and engineering assistance for legacy and current equipment.
